While the job of a research scientist varies, most chemistry careers in research are based in laboratories, where research is conducted by teams following scientific methods and standards. 21905-86-2. Introduce a common compound, CAS is 21905-86-2, Name is Cinnoline-4-carboxylic acid, belongs to cinnolinecompound.
EXAMPLE 63f Synthesis of Cinnoline-4-carboxylic acid [2-((S)-2-imidazol-1-yl-1-pyridin-3-yl-ethoxy)-5-oxo-5,6,7,8-tetrahydro-naphthalen-1-yl]-amide (Compound 63f) The procedure in Example 63d step 3 was followed using cinnoline-4-carboxylic acid. The reaction was stirred at RT for 1 day and at reflux for 1 day. Purification by chromatography (SiO2, 5-8% MeOH/CH2Cl2 with 1% NH4OH) afforded the title compound as a foam (63 mg, 0.125 mmol, 44%). The structure was confirmed by NMR and mass spectrometry. MS m/z 505 (M++H).
Future efforts will undeniably focus on the diversification of the new catalytic transformations. These may comprise an expansion of the substrate scope from aromatic and heteroaromatic compounds to other hydrocarbons. Keep reading other articles of 21905-86-2., 21905-86-2
